Peru’s largest and most notorious energy project, known as the Camisea gas fields, lies deep in the reserve.

Owned by a consortium of foreign gas companies including Pluspetrol, Hunt Oil and Repsol, the project has now been granted permission to expand further into the area, despite the risk to tribal communities.

Crucially, the Nahua-Nanti Reserve acts as a buffer zone to another hugely important tourist attraction, the Manú National Park.

Recognized as one of the most biologically diverse places on earth, it is now feared further gas expansion plans could destroy parts of this UNESCO site.

Survival International’s Director Stephen Corry said today, ‘Tourists visiting Machu Picchu, who have an interest in Peru’s history and culture should take notice of these adverts and take action. Uncontacted tribes’ land must be protected, or they too will be wiped out, like the Incas were in the 17th century.’
